The jury is expected to hand down a verdict later Thursday or on Friday. The original trial found Nancy Kissel, a native of Adrian, Mich., guilty of killing her husband seven years ago. A judge later ordered a retrial.
Prosecutors say Kissel gave her husband a sedative-laced milkshake and then bludgeoned him with a metal ornament. The defense says Kissel was a battered wife acting under diminished responsibility.
Kissel's lawyers said she was guilty of manslaughter, not murder.
The first trial grabbed worldwide attention as it described the breakdown of a wealthy expatriate marriage.
